pactum VS uvu

PactumJS with JSON Schema integration.

Pactum is quite powerful allowing different kind of E2E tests, you pass the base URL to make a request and assert over the response, it has more assertion functions than supertest and also supports GraphQL

You will use Strapi to build the back-end of a simple To-Do list application. Then set up PactumJS, a testing framework to create automated tests for our back-end. We will learn the basics of Strapi while creating the back-end, dive into the basics of automated testing using PactumJS and learn about making different requests and validating the responses.

Either that, or using a tool that in my opinion is more robust, like pactum

PactumJS abstracts the challenging parts to write tests in an easy and fun way and ultimately making API Integration testing super easy.

Last but not least important are ava, uvu and tape; they are a really light and fast test runners.

Vitest: A Vite-native unit test framework. (alternative: Jest, uvu)

Most important here is not to forget to include test.run() at the end… I’ve done that a few times 😅. Notice how we are able to use aliases in lines 1–3. You can see the full range of assert methods available in the uvu docs.

For the past few weeks I’ve taken the (arguably pointless) work of migrating Felte from using Jest to uvu. This is a really tedious work by itself, but one of details that would have made this work even more tedious is that Jest prefers assertions to the style of expect(…).toBe* while uvu gives you freedom to choose any assertion library, although there’s an official uvu/assert module that comes with assertions to the style of assert.is(value, expected).

Hello everyone, I'm using uvu for testing. And installed c8 for coverage. Yet it doesn't seem to be able to pick up test .svelte files. Does anyone knows how to achieve this or any other way of getting .svelte files coverage? Thanks

Yes! There’s even an example test written for the svelte counter demo in the repo’s examples!

uvu is what I’d recommend.

I really enjoy Ava [1] or anything assert-tape-like [2]. "uvu" [3] is getting a lot of love lately, but it's very feature limited and much of it's touted advantages are at the detriment to feature set.

Jest is great for front-end (or full stack integration) testing, but I feel it's specialized for that use-case and doesn't always play nice with backend/middle-tier testing needs.

For Node, I lean towards UVU by @lukeed due to its simplicity. Its lightweight, fast, supports ESM out of the box. It feels like an easier to setup modern Mocha (without the wide array of plugins).
